CARACAS, Venezuela 
Police and supporters of President Hugo Chavez clashed with students in cities across the country Monday during protests over the government forcing an opposition channel off cable TV. One youth was reported killed and 16 people suffered injuries.

The biggest confrontation occured in Caracas, where police fired tear gas and plastic bullets to scatter thousands of students who tried to march on the headquarters of Venezuela's state-run telecommunications agency. At least six demonstrators and a journalist were treated for injuries.

In the western city of Merida, a youth was killed during fighting between anti- and pro-Chavez forces and clashes when police tried to separate the rival groups, Justice Minister Tareck El Aissami said late Monday.

Merida Gov. Marcos Diaz told the state-run ABN news agency that the victim was a high school student named Jossimir Carrillo Torres. Nine police officers were injured in the melee, El Aissami said.

Demonstrations erupted over the government ordering cable companies to drop Radio Caracas Television Internacional early Sunday. RCTV had defied new rules requiring local cable channels to carry mandatory programming, including some of Chavez's speeches.

Police fired tear gas as protesting students tried to approach the headquarters of the state telecommunications agency, where several hundred Chavez backers gathered to support the government's action. Some were seen throwing rocks and bottles at anti-Chavez protesters.

"Freedom of expression is a right that we all embrace, and it must be defended," said Alejandro Perdomo, 19, who accused Chavez of attempting to silence his critics.

The crowd chanted: "It will return, Radio Caracas will return!"

Students also staged street demonstrations in the cities of Barcelona, Maracay and Valencia.

The government says RCTV violated recently approved regulations that require two dozen local cable and satellite channels to televise Chavez's speeches whenever he deems it necessary.

The channel, which has been fiercely critical of Chavez for years, did not transmit the president's speech Saturday to a rally of supporters.

Five other channels were also dropped from cable, but none of them were as widely watched as RCTV.

Diosdado Cabello, director of Venezuela's telecommunications agency, defended the government's actions, reiterating Monday that RCTV and the other dropped channels violated the law.

"They don't want to comply with the law, they want to do whatever they want," he said.

During an interview broadcast on state television, Cabello said one of the removed channels, TV Chile, had contacted the telecommunications agency to "correct things" and discuss its possible return to the airwaves.

RCTV was forced to move to cable in 2007 after Chavez refused to renew its license for regular airwaves, accusing the station of plotting against him and supporting a failed 2002 coup.

At least five students suffered minor injures or breathing problems from tear gas during Monday protest in the capital, said Enrique Montbrun, director of health services in the capital's Baruta district. Caracas Police Chief Carlos Meza said a government supporter was hurt when hit in the face with a bottle or rock. A journalist working for AP Television News suffered minor head injuries from a hurled object.
